Cisco Unified Communications Manager SNMP Trap Agent denial of service
| cucm-snmp-dos (42420) |  Medium Risk |
Description:
Cisco Unified Communications Manager (CUCM) is vulnerable to a denial of service, caused by improper handling of packets by the SNMP Trap Agent service. By sending specially-crafted UDP packets to port 61441, a remote attacker could exploit this vulnerability to cause the service to restart and core dump, resulting in a denial of service.
